DOOR-FASTENING DEVICE.

Application filed October 22, 1921. Serial No. 509,453.

To all 207mm it may concern Be 1t known that I, VINonNzo D. Tns'rn, a

citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented newand useful Improvements in Door-Fastening Devices, of which the following is a specification.

This invention relates to certain new and useful improvements in door fastening devices and while it is well adapted for general use it is particularly designed. for use as an emergency lock, whereby travelers or other persons may quickly and securely fasten a door in a closed position.

It is an object of the invention to provide a strong, durable device of simple construcpocket. i j

A still further object is to provide a device of the character above indicated which may be used on practically every type of door without injuryto the door or door frame. j p

The above and additional objects are accomplished and other endsare attained by the novel construction combination and arrangement of parts hereinafter described and illustrated in the accompanying drawing, wherein I have shown a preferred embodiment of the invention, it being understood that changes and modifications may be made or substitutions resorted to which come within the scope of the appended claims.

In the. drawings similar characters of reference are employed to designate like or similar parts as the same are shown in any of the several views and in which Figure 1 is a side elevational view showing a device constructed in accordance with this invention.

Figure 2 is a perspective view of a door jamb showing the manner of securing my improved device to the socket plate.

Figure 3 is a perspective view showing a portion of a door and door jamb with the door secured in a closed position by my improved device.

Figure 4: is a horizontal sectional view taken as indicated by the line 4Ci of Figure 2.

Figure 5 is a perspective View of a strap member adapted to be used in connection with my improved device for the purpose of looking a door from the stop side thereof.

Figure 6 is a horizontal sectional view showing my improved device as used in connection with said strap member.

Turning now to a detailed description of the invention with reference'to the drawings, the numeral 1 denotes the stem or body of my improved device. The numeral 2 denotes abit or anchor which projects radially from said stem at a point adjacent the end thereof. The central portion of the stem is cylindrical but it is flattened adjacent the bit end so as tobe easily positioned between the door and door jamb. The anchor 2 comprises a flat elongated member which is integral with'said stem and is positioned thereon so as to project from the Hat side thereof at a right angle; thereto. The anchor 2 is notched at each end to provide a. narrow base 2 and arelatively larger head 2 which overhangs said baseat each endto form the relative sharp end portions 2. The center'portion of the stem is provided with the screw threads'B. A swivel jaw 4; is positioned on said stem so as to slide freely thereon. The numeral 5 denotes a wing nut which is adapted to fit the screw threads 3 and is positioned onsaid stem so as to engage said threads and force the jaw 4 toward the bit end of the stem. The outer end of the stem is flattened and provided with an eye 6 for the purpose of securing a key ring chain or other carrying device thereto. The jaw 4 comprises a cylindrical collar t having a web i projecting radially therefrom. The cylindrical portion 45 is cut away as at 4 for a purpose which will be hereinafter described. The numeral 8 denotes a door and the numeral 7 a door j amb. The numeral 9 denotes a socket plate which is secured to the j amb so as to surround the bolt receiving aperture therein. The numeral l0 denotes a door stop and the numeral: 11 is used to indicate a flexible strap which is used in connection with my improved device to lock a door from the stop side thereof. The member 11 comprises a thin stripof copper 11 or similar material which is provided with an elongated aperture 11 The anchor member 11 is pivotally secured to-one end of the strap 11. The anchor member 11 is provided with hooks 11 and is slit at ll to receive the strap 11* which is secured therein by means of the pin 11".

In use the door 8 is opened and the bit 2 is entered in the bolt receiving socket of the jamb. The stem 1 is then swung to a horizontal position which positions the end portions 2 of the anchor member 2 behind the socket plate 9 as clearly shown in Figure 4. The door is then closed and the jaw 4 is pushed inwardly on said stem so that the forward edge thereof is in contact with the door 8. The wingnut 5 is then screwed down against the jaw 4 to tightly secure the same against said door.

It will thus be seen that the door is held in a closed position so that it cannot be opened from the other side thereof.

In using my improved device to look a door from the stop side thereof the strap member 11 is secured to the door by engaging the'hooks 11 in the latch socket of the door lock as shown in Figure 6. The strap 11 being of copper or similar material is easily bent around the stop 10; the anchor 2 is then positioned in the slot 11 in said strap and the jaw 4 is positioned against the rabbet face of the jamb. The wing not 5 is then screwed down against the 4 exerting a pull on the strap member 11 and securely holding the door in a. closed position.

' tors-Patent is 1. In a device of the class described, a stem, the central portion thereof provided with a screw thread, one end portion thereof being flattened, a longitudinally disposed bit projecting at a right angle from said flattened portion at a point adjacent the end thereof, said bit comprising a base having an overhanging head which projects from each end thereof, a bit projecting from said end portion, said bit provided with sharp prongs and adapted when placed in a vertical position to be entered in the opening in the socket plate, ofjsaid door jainb, said prongs arranged when the stem is swung to a horizontal position to engage the under face of said socket plate and anchor the stem thereto; a wing nut operatively positioned on the said threaded central portion and a swivel jaw mounted on said stem between said nut and said bit subst-antially as and for the purpose herein set forth.

2. In combination with a door and a door jamb', a stem having a flattened end adapted tobe positioned therebetween, an anchor on said stem, a head on said anchor, said head adapted when placed in a vertical position to be entered in the opening in the socket plate of said door jamb and adapted to engage the under side of said plate when the stem is swung to a horizontal position; a swivel j aw mounted on said stem and means to move said jaw inwardly against said door and secure the same in position thereagainst.

In testimony whereof I have hereunto set my hand.
